Galvanised Square Twist Nails 40 × 3.75 mm (1 kg pack)

These square‑twist nails feature a 40 mm length and approximately 3.75 mm shank diameter, manufactured with a twisted shank design to provide enhanced pull‑out resistance compared with smooth nails. They are finished in galvanised coating for moderate corrosion resistance, making them suitable for sheltered or semi‑exposed building applications.

The twisted‑shank profile is ideal for use in fixing builders’ metal work, joist hangers, straps and similar structural connectors, where reliable anchoring is critical. Supplied in a 1 kg bag, this pack offers a trade‑ready quantity for on‑site use or general timber‑to‑metal fixings.
